Safety Information

∙Remove test leads from the meter before you open the battery door.

∙Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged test leads before you use the meter.

∙Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced.

∙Do not operate the meter around explosive gas, vapor, or dust.

∙Use only a single 9 V battery, properly installed in the meter case, to power the meter.

∙When servicing the meter, use only specified replacement parts.

Caution

To avoid possible damage to the meter or to the equipment under test, follow these guidelines:

∙Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.

∙Use the proper terminals, function, and range for your measurements.

∙Before measuring current, check the meter’s fuses. (See "Testing the Fuses".)
